zh-CN:Kernels/Compilation/Arch Build System
The Arch Build System can be used to build a custom kernel based on the official linux package. This compilation method can automate the entire process, and is based on a very well tested package. You can edit the PKGBUILD to use a custom kernel configuration or add additional patches.

If you have already a kernel .config file, uncommenting one of the interactive config tools, such as nconfig, and loading your .config from there avoids any problems with kernel naming that may otherwise occur - except in the case of at least make menuconfig. See note.

Note: If you uncomment and use 'make menuconfig' in build(), then use the menuconfig gui to load your existing config, you will run into problems with conflicting files in the end package. This is because you will overwrite the default config that PKGBUILD has modified to provide a unique install path, specifically the LOCALVERSION and LOCALVERSION_AUTO config options. To fix this, simply re-set LOCALVERSION to your custom kernel naming and LOCALVERSION_AUTO=n while still in menuconfig. For details, see https://bbs.archlinux.org/viewtopic.php?id=173504

Note: If you uncomment return 1, you can change to the kernel source directory after makepkg finishes extraction and then make nconfig. This lets you configure the kernel over multiple sessions. When you're ready to compile, copy the .config file over top of either config or config.x86_64 (depending on your architecture), comment return 1 and use makepkg -i. But do not use this for custom patches; put your patch commands after these lines. If you do patch manually bztar unpack and replace your patch.

Compiling

You can now proceed to compile you kernel by the usual command
makepkg
If you have chosen an interactive program for configuring the kernel parameters (like menuconfig), you need to be there during the compilation.

Note: A kernel needs some time to be compiled. 1h is not unusual. On recent systems with a SSD it usually takes less than ten minutes.

Installing

After the makepkg, you can have a look at the linux.install file. You will see that some variables have changed. Now, you only have to install the package as usual with pacman (or equivalent program):

# pacman -U <kernel_package>

Boot Loader

Now, the folders and files for your custom kernel have been created, e.g. /boot/vmlinuz-linux-test. To test your kernel, update your bootloader (/boot/grub/menu.lst for GRUB) and add new entries ('default' and 'fallback') for your custom kernel. That way, you can have both the stock kernel and the custom one to choose from.
